An official said terrorists used rockets and other weapons to kill six people including a senior police official in Pakistan's volatile northwest.
The Sunday incident occurred in Lower Dir, a district near the Afghan border.
Government official Syed Mohammed Javed said terrorists attacked a group of police who were chasing them after a kidnapping. The dead included the district police chief, Khurshid Khan.
Terrorists routinely attack security forces in Pakistan's northwest region bordering Afghanistan.
Dir sits next to Bajur, a region where the Pakistani military has fought insurgents over the past six months.
